Everyone knows about the horrors of the distant region called Zalesye, Erdey, Semigradye or Transylvania. But few know how it all began...

Vsevolod, a two-armed fighter of one of the hidden Watchmen who guard not the borders of the principalities, but the cherished line, drawn since ancient times by blood between human and non-human habitations, goes to Watch. It is he who must lead the reinforcements to the west, to the Teutonic castle built on the edge of the Ugric kingdom, for the Raid has begun. And the very embodiment of evil - the Black Prince, the Black Gospodar, Baravr, Sholomonar, Nachtritter - is preparing to enter the human habitation.
